I come, once again looking for a tutorial. It seems like my discrete math class is lacking in explanations for more complex (to me) problems. My question is:
Compute the value of the following alternating sum and show all your work.
Leave expressions of the form $m^n$ in your answer without attempting to evaluate them. Solutions that rely solely on calculator computation of the terms of the sum are unacceptable.
Please do not answer the exact question, I would like to find the solution on my own. If someone could only show how to work this problem, I would be grateful. Thank you.
